Introduction

AI Translation

BD9G401EFJ is a buck converter with built-in high side MOSFET. It has an input voltage range of 4.5V to 42V. Current mode architecture provides fast transient response and a simple phase compensation setup. The IC is mainly used as a secondary side power supply: for example, a step-down output of 3.3V/5V can be produced from voltage power supply such as 12V or 24V. In addition, it has a synchronization function with an external CLK that provides noise management.

Features

AI Translation
  • AEC-Q100 Qualified
  • Integrated Nch MOSFET
  • Synchronizes to external clock 250kHz to 500kHz
  • ON/OFF Control through EN Terminal (Standby current of 0μA)
  • Small package(HTSOP-J8ES)
  • LowDrop Out operation

Applications

AI Translation
  • Consumer devices in general that has 12V / 24V lines
  • Automotive applications (Audio system, Navigation system, etc)
  • Industrial distributed-power applications
  • Entertainment equipment
